    What is the value you are trying to set it to ? The value you have in the 32 bit unsigned integer is being interpreted by the Code composer studio editor. I would recommend looking at the Param structure to see what 16 bit value has been set in the Param structure (as shown in figure 3 here).  or define the variable as unsigned short and then typecast it to (int ) if the API needs you to pass an int.
